. pensive device of the character specified,

by means of which an automobile or like vehicle may be lifted clear of the ground or other supporting surface and held in such position aslong as may be necessary, and wherein the device is capable of adjustment for different heights.

In the drawings :Figure 1 is a side View of the improvement in place beneath an automobile and in position for raising the same, the automobile being in section, Fig. 2 is a similar enlarged view of a portion of the device showing the automobile raised, Fig. 3 is a plan view of the improved jack, Fig. 4; is a perspective view of a portion of one of the rear supports, Fig. 5 is a perspective view of a portion of the front support, and Fig. 6 is a similar view ofthe base or support for the ack.

The present embodiment of the invention comprises a front and a rear support, each of the said supports being of channel form, and comprising a cross bar or base 1, and arms 2 arranged at a right angle to, the base or the body and integral therewith.

A bar 3 is slidable in the channel of each of the arms and each bar is provided with a longitudinal series of openings 4:, one of which is designed to register with an opening in the arm 2, and a pin 5 is provided for engaging the opening to hold the bar in adjusted position with respect to. the arm.

Each of the arms 2 and the adjacent bar 3 forms a telescoping or extensible and contractible arm, and a rear axle support is connected with the upper end of each of the bars 3. Each of the said supports is in the form of a plate 6, having spaced ears 7, each ear being perforated 'to register with a perforation in the upper end of the bar 3, and a bolt 8 is passed through the register ing openings and is engaged by a nut 9. for holding the bolt in place.

Each of the plates. 6. is provided with longitudinally spaced openings 10 for en gageinent by the threaded ends of a shaped clip 11, the said clip being adapted to engage over the rear axle with the axle between the clip and the plate 6, and nuts 12 are threaded on to the arms below the plate for holding the clip to the plate.

The front support is similar to the rear support so far as the base is-concerned, the said base consisting of a cross bar or portion 13 and arms 14 of channel shape and bars 15 are mounted to slide in the channels of the arms, each bar corresponding in all ,vided with spaced openings 21.

respects to the bar 3 before mentioned and being held in adjusted position by a bolt 16. The front axle support is in the form of an angle plate, consisting of two portions 17 and 18 arranged at a right angle with re spect to each other, one of the said portions 17 having spaced ears 19, while the I other portion 18 is provided with a transverse bearing 20, and the portion 17 is pro- The ears and the 19 are perforated as shown at ears l9 engage-opposite sides of the upper end of the bar 15, and are pivoted to the barby means of a bolt 23.

Nuts 24 are engaged with the bolts, the said bolts and nuts pivotally connecting the angle plates 1718 to the bar 15. A clip 25 of approximately U-shape is adapted to be passed over the front axle, and the threaded arms of the clip are passed through the openings 21 of the portion 17 of the angle plate and are engaged by nuts 26 below the said portion.

An approximately V-shaped bracket 27 is connected with the portion 18 of each of the an le plates, the ends of the said bracket being ent angularly to fit against the innor ends of the bearing 20 as shown at 28 in Fig. 3, and a shaft or rod 29 is passed through the alined bearing and through openings in the lugs 28, the said shaft or rod extending between the angle plates. Clips 30 are secured to the base portion of the rear support, by means of bolts or rivets 31, and similar clips 32 are secured to the cross bar 13 of the front support in like manner.

Chains 33 orother suitable flexible conductors connect the adjacent clips of the supports, each chain being connected with the clip 30 of the cross bar 1 of the rear support and extending forwardly to a connection with an eye 34 of each adjacent clip 32 of the cross bar of the front support. Each of the clips 32 is provided with an eye 35 at the front of the cross bar, and a hook 36 of a rod 37 is engaged with each of the said eyes, the rods 37 extending forwardly and inwardly to a connection with the base of the lifting jack, to be described. The said base is in the form of a plate 38, having at its front end laterally spaced perforated ears 39 and having on its upper face an upwardly extending lug 40, the said lug being provided with a transverse opening 41. The

. front ends of the rods 37 extend rearwardly alongside the face of the adjacent lug 39, and a bolt and nut 42 connects each of the said rods with the adjacent lug, each of the bolts passing through a ring or the like on the end of the rod and through the opening of the lug.

A jack is arranged between the base 38 and the bracket 27, the outer member or socket 43 of the jack being pivoted to the lug, by means of a bolt 44, which passes through spaced ears 45 on the base 46 of the jack. The standard 47 of the jack is threaded into the socket, and a collar 48 is secured to the upper end of the standard, by means of a pin 49. The operating arm 50 of the jack is provided with a bearing lug 51, encircling the standard above the collar, the said arm having a socket for receiving a lever 52 for turning the arm to rotate the standard. The standard 47 is hollow and internally threaded and a rod 53 is threaded into the hollow. The upper end of the rod SEE-passes through an opening in the body of the bracket 27, and a wing nut 54 is engaged with the upper end of the rod above the body of the bracket. A gear wheel 55 is arranged on the rod 52, and the arm 50 is provided with a pawl for cooperating with the said wheel. It will be understood that any desired form of jack may be used, the said jack being arranged between the bracket 27 and the lug 40 of the jack base 38.

In operation, the device is arranged be neath the car 56 as shown in Fig. 1, each of the supports being arranged with its cross bar or base in rear of the adjacent axle and below the same, the arms 2 and 14 of the supports being inclined upwardly and forwardly. The bars 3 and 15 are then adjusted until the plate 6 and the portion 17 of the angle plates 17-18 rest against the lower face of the adjacent axle. The clips 11 or 25 as the case may be, are then engaged 'with the plates ofthe support. The clips 11 engage the rear axle 57, while the clips 25 engage the front axle. When in this position, the lever 52 is operated to extend the jack, and the car will be pushed rearwardly and lifted, swinging upward on the telescoping arms of the supports as shown in Fig. 2. When the said telescoping arms are vertical, the action of the jack is stopped, and the car may be held in this position as long as may be desired. 7

It will be noted from an inspection of Fig. 2, that the rod 35 has the end adjacent to the wing nut 54 polygonal in cross section, and that a shoulder 58 is provided, the said shoulder bearing against the body of the bracket 27. When not in use, the jack is disengaged from the bracket 27 by removing the nut 54 after which the rod 53 may be withdrawn. The bracket 27 is then swung up into the dotted line position of Figs. 1 and 2, and the front and rear supports are lifted as also shown in the said figures in dotted lines. The rear support is engaged with the resilient catch 59 on the body, the said catch holding the support in inoperative position. The front support is engaged with a similar catch 60. The device is thus always in position for use and may at any time be dropped in the full line position of Fig. 1. The jack, the support for the jack, and the rods 37 may be carried in thetool box or in any other desired place when not in use and the bracket 27 is held in the dotted line position of Fig. 1 on a catch 61.

It will be also noted that the body or socket 43 of the jack is not pivoted directly to the lug 40. The base 62 of the socket rests in a channel plate 63, which carries the lugs 45 pivoted to the lug 40. The jack may be thus used as a single jack for lifting one of the wheels or any other purpose that a jack may be used. When intended to be used with the lifting device, the base of the jack is merely inserted in the channel of the plate 63 and it is ready for use.

It will be seen that the improved device is always in position for use, being connected with the axles at all times. On this account, and because of the fact that it may be used with an ordinary jack, the device may be brought into operation at any time whether on the road or at home.
